Hi folks, got an issue with extraction issues. Brass seems to hang up under claw on bolt. Shot NORMA ammo 150 gr. Disassembled bolt and did not see any indications that any mods for improved springs for extractor or ejector. Did see a little bit of wear on the sides of the extractor claw. Only fired 20 rounds total.
Sure this problem has been discussed previously, but kindly humor me cause I am new on searching the site and couldn't find the topic.
Particulars which I think may have a bearing:
Built using Black Rain billet upper and lower set (Fallout)
Black Hole 24" bull barrel with M4 feed ramps. Rifle length gas port and using an adjustable gas port from Black Rain
MAGPUL PRS stock and DPMS installation kit (rifle length buffer spring and buffer)
DRD Bolt carrier Assy (CGNB)
Best guess on my part the least expensive approach is to mod the bolt with improved springs for the extractor and ejector(perhaps from Tactical Springs & Machine Gunners Lube)
Change out the buffer spring with one from Sprinco
Get a new Bolt. Not sure of the quality of the DRD. Did not do my homework prior to buying the thing and impulse bought with some other stuff at gun show. On me, try not to make that mistake again. Should have known better. One to chalk up as experience. Looking at these ( IN STOCK AR10 / 308 parts - Red Barn Armory
OUT OF STOCK AR .308 Complete Nitride Bolt Carrier Group) or JP bolt carrier assy and buffer spring. Probably a stupid question. Using a different bolt assy in another manufactuers carrier?
Look forward to learning something. Thanks
