    Ivan's done playing.

    US-Russian relations even back then were sparse at-best, because Russia is so geographically-isolated and not well-established into the trade routes as a result. It’s also extremely cold there with no deep water sea ports, and the only warm ports are in Krim (Crimea). Britain, France, and...

    Question about 13.9in vs 14.5in

    The companies are going to hold themselves in compliance with the infringements because they don’t want to lose their manufacturer’s license (another infringement). What I’m talking about hasn’t been mentioned before to my knowledge, but just an insurance policy if someone is worried about it...

    Classified Defense R.A.T barrels

    In the M4 TDP, the index pin is just pressed into the extension. It isn’t supposed to breech the barrel tennon threads, but some manufacturers do that because they thought it was a reasonable idea to ensure the extension wouldn’t come loose. The real solution to extensions not coming loose is...

    Help Identify BCG

    Looks like a side-charger to me, hence the threaded hole up front with the adjacent holes for the handle indexing points. Just my first guess based on what I’m seeing. Can’t have ejection port doors on right side chargers and no need for FA when you have a handle attached to the carrier anyway.

    Classified Defense R.A.T barrels

    Early-on when nitriding became a new craze in the US civilian market, as if it was something new, some of the batches of barrels were having issues with salts getting between the extensions and shoulders. When I do muzzle device work, I clamp the barrel in the vice with insulators, never apply...

    Question about 13.9in vs 14.5in

    If I lived in a region where ATF ASACs and SAs were very hostile to real Americans who are exercising their rights, I think I would take my P&W jobs to a 3rd party (especially a retired investigator or someone with expert witness background related to firearms cases), and have them declare in...

    A tale of three Larue's (Large frame review Part 1 - OBR)

    I did not know they were using sprung firing pins in the Large Frames. KAC went that route as well. It really is the way for the .308/.260 Rem/6.5CM class of cartridges. Unsprung LF guns can have a surprising amount of firing pin velocity/momentum to the rear, which beats the crap out of FP...

    Update Dimpled: [Modding an LMT MRP CQB Quad w/ Riflespeed etc]

    If I could go back in time, I would show Stoner the MRP upper receiver and quick-barrel change system to make it the standard out of the gate. They didn’t have CNC yet though, and machining that upper would have been a bit of a witch in mass-production, so it would have been anachronistic. A...

    Ivan's done playing.

    Part of ideological warfare is creating chaos, confusion, disunity, and distractions so the prime actor spewing the lies can maneuver. From the Russian intelligentsia perspective (an old and dying breed from the Cold War), they are a 1000yr-old civilization who see themselves as...

    Update Dimpled: [Modding an LMT MRP CQB Quad w/ Riflespeed etc]

    A buddy of mine just had a shop do a Noveske 12.5” Grendel MRP conversion for him. Looking forward to seeing it come together.

    A tale of three Larue's (Large frame review Part 1 - OBR)

    This is a great pic showing what I’m assuming are the HP .068” Firing Pin aperture bolt vs a legacy .086” FP aperture bolt: Have you ever seen ejector channel extrusion signs with that nice, large ejector? It seems like moving it outwards from the bore line would help alleviate brass...

    Is Arken CS non-existent?

    But I thought this was for your dad’s .22 Rimfire. Is it an NRL .22 where you want a full-featured scope or a plinker?

    Federal red flag / disarmament center

    Covid mandates definitely showed everyone what level of tyranny cowards were willing to enforce just by simply “following orders”. The real problem underlying that is conformity training in public school. If you want to continue cowardice of conformity, continue sending your kids to school...

    You guys know that Leupold has entry-level scopes, right?
