Gast gun mechanism9/1/2023 ![]() The original production run of CETME-LC carbines was done near the end of the gun’s service period, and the receiver stamping tooling was getting old and worn. The firing pin spring is not nearly strong enough. However, in this case we have a problem, thanks to the poor spring quality endemic to the CETME-L. No problem, if the other parts of the design are adjusted accordingly. What this all leads to is an increase in bolt velocity. The spring tension was also changed, and the bolt carrier weight was reduced by about 3 ounces. So the LC model has its recoil spring assembly moved up to the area of the charging handle tube. Because the recoil spring in the normal rifles extends deep into the stock, it must be changed if the rifle is to have a different type of buttstock. The LC is the short ( corto) carbine version of the gun, with a 12.6″ barrel and a collapsing stock. There is, however, one other model of the rifle – the CETME-L C. That is a totally non-mechanical difference – it has no impact on how the rifle functions. Now, the LV model is identical to the standard CETME-L except for the rear sight block, which includes a STANAG optics mount not present on the regular CETME-L rifle. As you may or may not be aware, I recently built a semiauto CETME-LV rifle using a parts kit imported by Apex Gun Parts and an 80% flat from Hill & Mac Gunworks. ![]()
