CAUTION: Always check that ammunition is clean and undamaged before using. Loading damaged ammunition into the chamber could damage your rifle and could result in personal injury, death or damage to property.

1. Use only ammunition for which your firearm is chambered (Photo 29-A).

2. With front of magazine forward, place a round between the lips of the magazine with the bullets pointed forward. Press the round until the magazine lips retain it. Place the next round on top of the last and repeat until desired number is loaded (Photo 29-B)(Photo 29-C).


1. Pull back on the charging handle to cock the hammer, and then press in on the bottom of the bolt catch to lock back the bolt carrier assembly (Photo 29-D).

2. Return the charging handle fully forward until it locks and remove finger from bolt catch (Photo 29-E).

3. Set selector to "SAFE" position (Photo 29-F).

Smontaggio Finto Bolt Catch

With the bullets facing forward, insert loaded magazine into magazine well and push it in until it stops and is retained by the magazine catch. Tap the bottom of the magazine in an upward motion to ensure that the magazine is seated tight. (Photo 29-G)

With the rifle pointed in safe direction press in on the top button of bolt catch. This will release the bolt and carrier and move a round into the chamber. The rifle is now loaded with a round in the chamber and the hammer cocked. (Photo 29-H)

Make sure safety selector is still on safe. (Photo 29-I)

1. Set selector to "SAFE" position. (Photo 30-A)

2. Press magazine catch button and remove magazine. (Photo 30-B)

3. Pull charging handle to rear and push in lower portion of the bolt catch. If a round had been in the chamber it would have been ejected. Make sure to visually check to make sure that the chamber is empty. If last round in magazine had been fired, bolt and carrier should already be held to the rear, if the magazine was in place. (Photo 30-C)


Firing Preparation

Before firing your rifle, practice your stance, aim, rhythm and breathing for a steady aim with your firearm unloaded. You should practice firing on a range before going hunting or before using your firearm for any other type of shooting.

1. Always wear eye and ear protection when firing your weapon.

2. Load firearm as previously described.

3. Grasp firearm with one hand on handguard and other hand on pistol grip with trigger finger resting along side of trigger guard. Raise firearm and pull buttstock firmly into shoulder.

4. Aim by aligning target with your scope. (Scope not included)

5. Move selector to "FIRE".

6. Keeping steady aim, place trigger finger on trigger and gently squeeze until trigger releases hammer. Do not jerk trigger as you will disturb your aim and ruin your accuracy. To fire the next round and subsequent rounds, all that is necessary is to release the trigger and gently squeeze the trigger again after every shot until you are finished firing or the magazine is emptied.

7. This is a semi-automatic firearm and is immediately loaded and ready to fire after each shot until the magazine is empty and the last round in the chamber has been fired.

8. Release trigger, remove finger from trigger and set selector lever to "SAFE." If you have fired the last round from magazine, the bolt and carrier will be held to the rear so that you can quickly reload by replacing the magazine or if not reloading, the chamber should be checked to ensure that it is empty.

9. WARNING: This rifle will fire a chambered round with the magazine removed.


Panther .308 rifles feature a Lo-Pro style upper receiver. These rifles have a Picatinny Rail on the top of the receiver.


This will accept Weaver based rings and mounts. Standard size rings will be sufficient for scopes with objective diameters less than 40mm. Larger diameter scopes, depending on the size of the objective lens, may need either a riser or high rings.

Remove Dpms Pivot Pin


Pivot Pin

Your DPMS rifle is based on a military rifle design and is very rugged but proper maintenance is necessary to keep it in good working condition. Field Stripping Disassembly (Make sure your rifle is unloaded, with no ammunition in the chamber.)

1. Bolt carrier assembly should be closed in the forward position.

Press the rear take down pin in from left of lower receiver (it may be necessary to use a punch as the fit between upper and lower receivers may be very tight.) Pull the pin out until it comes to a positive stop. A detent keeps the take down pin from falling out of the rifle.

Pivot the upper receiver and barrel assembly down and away from the lower receiver.

Press the front pivot pin in from the left side of lower receiver and pull out right side until it comes to a positive stop. A detent keeps the front pivot pin from falling out of the rifle.

You can now separate the upper and lower receivers.

Pull charging handle to rear and remove bolt and carrier assembly. (Photo 31-A)

Remove charging handle by gently pulling it backwards until you feel a slight resistance. Charging handle will fall free from the upper receiver. Do not force the charging handle, damage to the charging handle wings will occur.

To remove the firing pin, first you must remove the firing pin retainer. Push the firing pin retainer from right to left. Remove it by pulling the retainer pin all the way out of the carrier.

Pivot Pin


9. Tilt bolt face up and remove firing pin.

10. Push bolt in towards the carrier until it rotates and comes to a stop.

11. Remove cam pin by lifting it out away from bolt and carrier.

12. Pull bolt forward out of carrier. (Photo 32-A)

13. Depress buffer, maintaining pressure as buffer is under spring tension, to prevent it from being ejected when buffer retainer is depressed. Depress buffer retainer to permit buffer and spring to move forward and be removed from receiver extension. (Photo 32-B)

14. With a punch, remove the extractor pin from the bolt assembly. (Photo 32-C)

15. Remove the extractor and spring. DO NOT remove the spring from extractor! (Photo 32-D)

16. Press top of extractor spring for spring function. Do not strip your firearm further than previously described. If additional maintenance is necessary, consult DPMS or a competent gunsmith. Your rifle is now field stripped for cleaning. To reassemble, repeat procedure in reverse order.

Notes on the Panther .308

The .308 does use a different buffer and spring than the standard A-15 rifles even though it takes the same A-15 A2 stock.

Due to a number of calls and comments concerning AR-type rifles, we have incurred feeding problems with the following:

A) I.Israeli ammunition 2. Korean ammunition

We have heard and reviewed several reports of problems with many manufacturers' rifles using this ammunition. The problem appears to be the bullet contour and the overall length of the cartridge, which is contacting the rifling before firing. This is creating a gas port pressure and chamber pressure higher than recommended, therefore causing feeding and extraction problems due to the increased bolt carrier velocity. In addition, there is accelerated fatigue on internal parts. There are also indications that brass may be oversized, which could create an unsafe condition.

2. South African produced surplus

We have used this ammunition in the past for testing purposes and found that the brass is extremely soft and can "flow" into microscopic pores and grooves in the chamber, creating "sticky" extraction. This had been reported in many types of rifles, but is more prevalent in semi-automatic weapons.

C) Lacquer Coated Ammunition or Steel-cased, lacquer coated ammunition

The problem with this ammunition is the lacquer coating on the case. As the barrel heats up, the lacquer turns to a soft, varnish substance and upon cool down, becomes very solid and difficult to remove. This effectively creates an undersized chamber and creates understandable problems.

DPMS recommends the use of high quality, domestically produced ammunition for best results and highest accuracy. For plinking and practice, we recommend only domestic, commercially manufactured ammunition or high quality surplus NATO specification ammunition. Please note that the use of re-loaded ammunition voids the factory warranty as well as the use of the above-mentioned types of ammunition.

Your rifle is an investment and it only makes sense to choose quality ammunition for a quality rifle!


To achieve the best results for accuracy you should clean the chamber and bore after every round for the first 25 rounds and then every 10 rounds up to 100 rounds. It usually takes about 200 rounds per barrel for optimum accuracy. Please keep in mind that our barrels are production barrels not custom barrels. Accuracy is dependent upon many factors such as bullet weight, powder load, rifling twist, rifling lands, operator technique, etc. Our production barrels have achieved anywhere from 1/8" to 1 1/2" M.O.A. Obviously, we would hope that every production barrel would shoot 1/8" M.O.A., but with all of the above factors, we cannot guarantee a specific group size.
